TOILET BOWL.

Application filed October 12, 1923.

the type in which means are provided for carrying off objectionable odors directly from the bowl instead of allowlng theiuto pass into the room, and the ob ect of my invention is to devise improved means for this purpose which will be very efiective in carrying off said odors, which will be simple and cheap to manufacture, which wlll have a good appearance, which will not be un-- comfortable in use, and which will be perfectly sanitary.

I attain my object by means of the corn structions hereinafter described and illustrated in the accompanying drawings in which Fig. 1 is a side elevation of a toilet bowl, partly broken away, showing the seat there of in lowered position; and

Fig. 2 a section on the line 2--2 in Fig. 1 showing the seat in raised position the bowl being omitted.

L is a toilet bowl, and A a water reservoir, which is adapted to supply water to the bowl through the usual pipe B. The bowl will be of any ordinary type, and is provided with the usual flange N at the rear thereof. E are ventilating flues, preferably rectangular in cross section, the for-'- ward ends of which are secured to the flange N by means of bolts M. As the pipe B is usually located substantially midway of the width of the bowl, the fines E will prefer ably be located one at each side of the pipe B. The rear ends of the flues E may be connected directly with the vent D, which will usually be located in the wall of the building, but preferably connected with a common receptacle C with which the vent D communicates.

. The seat I is secured to the forward ends of the fines E bymeans of the hinges F. This seat I is of special construction, being preferably formed of aluminum or other light metal. The seat in the main is of concavo-conveX form in cross section. At the rear of the under side of the seat are formed partitions or baffles H, forming between Serial No. 668,216.

them a passage 0 adapted to communicate with the fines E. A depending flange or plate (3' is provided at the rear of the seat bet-ween the mouths of the fines E to cut off the space between the lines and prevent the passage of objectionable odors into the room.

Towards the front of the seat are formed the transverse projections or ribs J, which are adapted to hold the under side of the seat spaced from the upper edge of the bowl, and thus permit the ingress of air from the room to the bowl when the seat is occupied, as the admission of a certain amount of air to the bowl is necessary to cause proper ventilation through the vent D. The ribs J will preferably be provided with resilient bumpers K to avoid damaging the bowl.

When the seat is down, ventilation will be effected through the compartment 0, while if the seat is raised, ventilation will be effected directly through the mouths of the lines E. As the vent D will in practice be connected with a chimney or other flue in which there is considerable draft, there will always be a suction which will tend to draw the foul odor rising from the bowl into the dues E, instead of allowing it to pass into the room, even while the seat is raised, while when the seat is down and occupied, very little foul odor may pass into the room. The eiliciency of the device is greatly increased by the baflies H, which direct a large proportion of the air from the room, which enters the channel formed in the under side of the seat, into the bowl instead of allowing it to pass directly to the fines E, thus causing a circulation of air in the bowl itself which would not otherwise occur.

The seat will preferably be given a coating P of celluloid, or similar sanitary germ acid and sweat-proof material.

' From the above description it will be seen that I have devised a construction which will satisfactorily attain the objects of my nninicate with the month 01? the flue said partitions 'iorining baffles to direct air pass ing along the under side of: said seat into the bowl; and means on the under side of said seat adjacent the front thereof adapted to hold the under side of the seat spaced from the upper edge of the bowl to permit ingress of air into the bowl when the seat is occupied.

52. The combination with a toilet bowl of a pair of spaced vent fines each secured at one end to said bowl, and a seat hingedly connected with the said ends of the tines, said seat being substantially concave-convex in cross section; a pair of partitions forined across the under side oi said seat, to fol-n1 a passage, the rear end of which i. adapted to communicate with the mouths of the u s said partitions forming baliles to direct 1r passingalongthe under side of said seat into the bowl, a plate adapted to close that portion of the passage betv-reen the tines; and means on the under of the seat adjacent the front thereo; adapted to hold the under side of the seat spaced from the upper edge of the bowl to permit ingress oi? air into the bowl when the seat is occupied.

3. A toilet bowl having one end of? a vent flue secured thereto; a seat hingedly connected with said end of the vent flue said seat being substantially concave-convex in cross section; and a pair of partitions formed across the under side of said seat, one

at each side of the vent fine, to form a pas- ;e, the rear end or" which is adapted to communicate with the mouth of the line; and pair of transverse ribs on the under side of the seat adjacent the front thereof adapted to hold the under side of the seat spaced vfrom the upper edge of the bowl to permit ingress of air into the bowl when the seat is occupied, said partitions and ribs forming battles to direct air passing along the under side of said seat into the bowl and a common receptacle with which the other ends of said tines communicate.

4:. ii. toilet bowl having one end of a vent tine secured thereto; and a seat hingedl connected with said end of the vent flue, said seat having a channel formed in its under side; a pair of partitions formed across said channel one at each side or" the vent flue, to form a passage the rear end at which is adapted to communicate with the mouth of the fine, said partitions forming battles to direct air passing along the under side of the said seat into the bowl; and means on the under side of said seat adjacent the front thereof adapted to hold the under side of the seat spaced from the upper edge of the bowl to permit ingress of air into the bowl when the seat is occupied.
